Test Method: SATRA TM199

Water spotting - shoe care products

July 2021

SCOPE

This method is intended to determine the effect of a shoe care treatment, such as a polish or spray protector, on the resistance of a material to spotting damage by water. The method is applicable to any shoe care product which makes claims for water resistance or water repellency.

PRINCIPLE

Two drops of water are placed on an untreated test specimen and on a test specimen which has been treated with the shoe care treatment. After 30 minutes surplus water is blotted from one of the drops on each of the treated and untreated materials and any physical effects are observed. The other drops are left to evaporate for 16 hours and any physical effects on these and the samples that had been blotted after 30 minutes are observed. The physical effects are compared for the treated and untreated material.
